136,000 miles and I've done all the usual maintenance items you do on a used car you just picked up. New spark plugs and wires, distributor cap and rotor plus ignition pick up, timing belt, throttle body and MAF sensor cleaning, fuel and air filters, checked fuel pressure which is normal. Car has two issues.
1) On mostly cold starts, the engine runs rough and misses for about 5-10 seconds during which the exhaust smells quite rich. After that it smooths out fine. Thinking the injectors may be leaking when the engine is off or dumping too much fuel when first started.
2) Sometimes when idling, the rpms will rise way too high. Seems like something around 2-3,000 rpm. Also seems to happen mostly before it's fully warmed up but doesn't happen every time I drive it either. Could that be MAF sensor related? I see junkyard markings on the one it's got.
Car is pre even OBD1 so no plug in scan tool or codes to retrieve and give any direction. Car runs fine otherwise with good power and smooth running. Whoever said the older cars are easier to work on probably never worked on a fuel injected model.
